EGG-TESTER.

Specification of Letters Patent.

Patented Oct 8, 1912'.

. 'Application iledMay- 23', 1.910. Serial No. 562,953.

To allfw'wmiit may concern: 1

Be itknownthat I, DAvrnB. CONWAY,

*citizenof the United States, residing at' Fort Dodge', in the county ofWebster and" State,-of` Iowaf,/havei. invented certain new;I

' and useful lImprovements -in Iflgg-Testers,y

of which thefollowing is a speclfication.' ,f

Myinvention relates to'gg testers and` In these drawings, Figure 1 issides,"-

view; 2 is a central vertical sectiong.` Fig. 3, a -p'lan fof the devicewith the hood removed, .and Fig, 4 is a plan of the 'device i 1 with thehoodand tray removed.

Referring to the drawings, l representsa vertical tube having at eachextremity a'` screw-threaded band 2 riveted or otherwise. securedthereto. At 'the lower extremity of thehtube, thethreadsfofvthe band 2are adapted 'tb lbe screwed into a threaded mem ber 3 of a base-plate 4.At the opposite en d' this tube is adapted to be screwed to a coneshapedmember' 5 at 6. A removable eggretailning; tray 7 rests upon the member5 and the outerwwall of the tray is extended' slightly below the bottomof the tray so that 7 restsv a removable cone-shaped hood or cover8provided with a central opening at` the top thereof through which thecondition of the eggs may be seen. This hood has a vertical wall9` atits base and this wall is- `adapted to fit over and embrace the upperedge of the tray 7 to prevent lateral move'- ment of the hood upon thesame. The Vbottom of the tray 7 isprovided with suitable openings 10.The e gs are placed in compartments 11 within the tray 7 and theopenings 10 are arranged beneath the compartments. The interior of thetray 7 and@ the walls of the compartments are preterml ably darkened bypainting the same a dark color or by covering the same with feltolsyother material of a dark color.

Removably seated in the upper end of the tube l is a socket member l12for an'y electric bulb 18. The tubel is 'preferably made of paper,vulcanized rubber, fiber or Iother suitable insulating-material. Withinthe tube is `a removable electric battery 14.- and conducting` portion15 of the socket contacts with a conductor plate 16' connected to oneelement of the battery.` ',Ihe conductor is kept in contact with the'socket by means of the spring '17 which is of conductino' material andby means of'its conf ltact with the' conductor plate 18 establishes acircuitwith the threaded member 3. In

contact with this member 3 is' a-conductl ing strip 19 which leads to acontact finger 20 which is made of spring metal and ranged exteriorly ofthe tube.

Aj contact member 21 is arranged opposite the linger 20 and the currentisadapted to pass from i the socket of the electric bulb into the socketimember 12 and thence into the conducting `as theinger 20 is normallyout of contact `with the contact 2l and in order 'to close the circuitand thereby light lthe filament of i .tery is considerably lengthened.the extension will prevent lateral movement thereof upon the member 5.Upon the tray the bulb, the finger 20 is pressed against the `contact Z1and the circuit rem'a'ins' closed 'as' 'long as the said parts are heldin contact.

-Upon releasing` the finger, it will return vto its normal position andthe circuit be. lbroken.

By providing the normally open circuit, the period of usefulness of thebatyas are used principally1 in stores and hotels,

the tester may be connected to the electric lighting means of the storeor hotel and the separate battery dispensed with.

With my device it is unnecessary to emf'V ploy a reiicctor beneath theeggs. I

Having thus described my mventiomwhat I claim 1s:'
